HORACE L. KINGSLEY, OF RACINE, WISCONSIN.

P'LAT'FORM-GEAR FOR WAGONS.

SPECIFICATION forming part of Letters Patent No. 247,364, dated September 20, 1881.

Application tiled March 21, 1881.

To all whom it may concern Be it known that I, HORACE L. KINGsLEY, residing at Racine,in the county of Racine and State of Visconsin, have invented a new and useful improvement in Platform -Gears ior Spring-Wagons, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure lis a plan; Fig. 2, a side view. Fig. 3 is an under side view of the parts shown; Fig. 4, a detail; Fig. 5, a cross-section at lille m ot' Fig.3; Fix, a cross-section at line y of Fig. 3; Fig. 7, a modiiication. Figs; 3 to 7are enlarged.

My invention consists in aplatt'orm-gearthe principal bars ot' which are ot' metal,in U form, secured at the ends, ns hereinafter described and claimed.

In the draw-ings, A represents the two outside bars of the platform, which are made ot' iron, having an inverted U form, as shown in Figs. 3, 5, and G. B is the short center bar, which, as shown, is made in the same manner. The front ends ot' these bars are supported by means of a brace-bar, C, and their rear ends lit against the inside ot' the head-block D. Ihe end of the brace-bar C is bolted to the front ends of the side bars,A. 'Ihe rear ends ofthe side bars, A,are,as shown in Figs.3 and 4, secured to the head-blork or bar D by means of a strap of iron, a, having a screw-bolt, b, upon one end. These stiaps a are placed between the walls ot' the bars and bolted in place, the space on each side ot' the strap, and between it and the wall, being tilled with woodc or other suitable material. The bolts pass through the bars D, and by means ot' nuts the ends ot' the bar A are drawn into close contact with such bar D. The center bar, B, is secured at both ends in the saine manner.

In Fig. 7 I have the saine. parts A B C D secured together by straps of iron and bolts, which, though somewhat different in construction, perform the same oiice as the straps and bolts already described. As shown in Fig. each bar is connected to the bariD by means of two iron straps and bolts. a represents one of these straps on the outside of each bar A,

bent so as to fit against both A and D; and e represents other irons, formed, as shown, so as to iit on the inside of and between the bars A and B,and to come in contact, also,with the inside of the bar D. 'Ihese irons are bolted to the bars A B, and are' also bolted to the bar D by means ot' bolts f. When irons like d c are used I tit pieces of wood or other suitable material into the ends of the bars A B. The front end of the bar B can be secured to the bar C by means of a single strap, as shown in Fig.1; or two straps may be used, one on each side. li h are suitable pole-irons. The bearingcircle of the fifth-wheel is bolted directly on the bars A A B, and thus firmly supported at three nearly equidistant points.

I have shown an axle with the springs 011 which the platform is supported.

This construction furnishes a platform-gear of light and durable character. The llingpieces c,in connection with the cross-bolts and bolts b, insure durable and substantial connection of the U-form bars, and a rigid frame is formed having the upper surface of its bars level for receiving the bearing-circle.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentv l. In a platform-gear for wagons, the bars A B, made U-shaped in cross-section, and provided at their ends with plates bolted to their walls for securing them to the head-block and. brace, substantially as shown and described.

2. In a platform-gear for wagons, the bars A B, made U-shaped in cross-section, and pro vided with the plates a, secured between its walls, substantially .as and for the purpose set forth.

3. In platform-gearior wagons,the U-shaped bars A B, provided with filling-pieces c, and plates a at their ends, for connecting to the bar D and brace substantially as shown and described.
